چکیده    We present the pseudostate-close-coupling method using a non-orthogonal laguerre-l2 basis function for the calculations of electron-helium scattering. our method is a frozencore model of the target in which one of the electrons is restricted to the 1s he+ orbital. the non-orthogonal laguerre-l2 basis function has been applied in the intermediate energy region (30, 40 and 50 ev) for the electron impact elastic and excitation of the 21s, 21p, 23s and 23p states of helium. differential and integrated cross sections are calculated and compared with recent experiments. the present calculation (pc) results for each case are discussed and compared with other calculations. it is found that the results agree quite well with experiments and with the other calculations
